Error: Options {"loose":true} passed to babel-preset-es2015/lib/index.js

[agsci2017]

I'm submitting a bug report

• Library Version:
  aurelia-cli 0.27.0

Please tell us about your environment:

• Operating System:
  Fedora Workstation 25

• Node Version:
  6.10.0

• NPM Version:
  3.10.10

• Browser:
  all

• Language:
  ESNext

Steps:
Create project with "au new" using default settings(ESNext by default, with project dependencies installation).
Run project with "au run".

Current behavior:
/home/user/aurelia_project1/node_modules/babel-core/lib/transformation/file/options/option-manager.js:328
throw e;
^
Error: Options {"loose":true} passed to /home/user/aurelia_project1/node_modules/babel-preset-es2015/lib/index.js which does not accept options.

Expected/desired behavior:

Succesfull run on server(http://localhost:9000)

Remark:
if "au new" set to Typescript usage, everything is ok(server runs, i see "Hello world" message in a browser).
It seems that problem specifically with babel transpiler.

Localized the problem.
If you create a project using "au new" with long name("aurelia_project1") and then run "au run" you'll get an error("option {loose:true} passed to babel").
If you create a project using "au new" with simple name("aurelia") and then run "au run", tracing, building and server runs without any errors.

aurelia_project1 (err)
aurelia_project2 (err)
aurelia_projecty (err)
aurelia_project (err)
aurelia_projec (ok)
aurelia_proje (ok)
aurelia_proj (ok)
aurelia_projectrge6djghsdjhg3r3 (err)
aurelia_projdir (ok)
aurelia_projection_of_light (err)

It seems that name conflict with internal directory "aurelia_project" happens.
Project name that starts with aurelia_project causes an error.
